Recovery/Recycling Phase; Vacuum Phase - Launch VALUE-100 User Manual

RECOVERY/RECYCLING PHASE

1) Connect the hoses to the A/C system with the quick-connect couplings, bearing in mind
that BLUE must be connected to the low-pressure side and RED to high pressure. If
the A/C system is equipped with a single quick-connect coupling for high or low
pressure, connect only the relative hose.
2) Start the vehicle engine and switch on the air conditioner. Allow both to run for about
10 minutes with the passenger compartment fan at full speed.
3) Switch off the engine; if possible, keep the air conditioner fan running at maximum
speed for the entire recovery phase
4) Open the high- and low-pressure taps (or, in the case of a single coupling, only the
relative tap).
5) Press and hold the SEL key until the LED until the LED corresponding to "Recovery"
lights; then press START. At this point the RECOVERY/RECYCLING phase will begin;
the "Recovery" LED will flash. During this phase the amount of refrigerant recovered
from the system will be displayed, in kilograms. Upon completion of the recovery phase
the machine will stop and automatically discharge the used oil recovered from the A/C
system during recovery. The oil discharge operation lasts 4 minutes. If during this time
residual refrigeration fluid in the A/C system should increase the pressure, the machine
will automatically recommence recovering the refrigerant.
6) Switch off the air conditioner fan and if necessary turn the vehicle ignition key to the
full OFF position.
At this point, all of the refrigerant contained in the A/C system will have been recovered and
recycled; there remains to extract the air and the residual humidity from the A/C system by
creating a vacuum.

VACUUM PHASE

1) Upon completion of the RECOVERY phase the machine will automatically proceed to
the vacuum phase. It is nevertheless possible to start the vacuum phase directly by
opening the high- and low-pressure taps, pressing the SEL key until the LED
corresponding to "Vacuum" lights, and then pressing START. The preset vacuum time
is 25 minutes (recommended for the majority of A/C systems), but may be modified as
explained below. Press SEL until the "Vacuum" LED lights, then press ENTER; at this
point the first digit on the left of the display will begin to flash. Press the + key until the
desired digit appears. Likewise, press the ARROW and + keys to change the other
digits. When setting is complete, press the ENTER key to confirm the vacuum time
value.
2) During the vacuum phase, the display will clock its duration. Leave the machine
running until the display reads 0000 and the pump stops automatically.
3) Close all the taps and read the vacuum value on pressure gauges (A1) and (A2). Wait
for about 2 minutes, then check that the pressure has not increased during the interval.
An increase in pressure signals leaks in the A/C system. Locate and eliminate the
leaks; repeat the vacuum phase.
NEW OIL REINTEGRATION
1) Measure the quantity of oil extracted from the A/C system and check that the new oil
container (n) contains at least 20 cc more than this quantity
2) Open the high- and low-pressure taps (or in the case of a single coupling, only the
relative tap).
3) Open the tap of the new oil container and keep it open until the quantity of oil
extracted during the recovery phase has been replaced.
